Dem Bones, Dem Bones, Dem Chicken Bones

I am trying to find out the name of a certain chicken bone in the drumstick. One is a regular bone and the other one looks like a hat pin – thin, round at one end about the size of a pencil eraser, about 4 inches long and comes to a sharp point.
What is the name of the thin, sharp pointed bone?

It’s been years since comparative anatomy, but the bone you’re talking about is the bird equivalent of the second, smaller bone in the human lower leg. Just like in humans this bone is the fibula; the tibia is the large bone most of us associate with the drumstick in chickens or in the case of a human, the shin.

And yes, if you are wondering the thigh bone in both the chicken and a human is the femur.
